AMERICAN LEPIDOPTERA. 311 lines of the under surface, the more ohscurely colored upper surface (which contrasts so much the more forcibly with the paler and bright hue of the under side) and by the straighter external margin and more prominent angles of the primaries, while the antennae seem proportion- ally longer, the <; club" more prominent. We have heard of the discovery of this species in Michigan and look to hear of its capture in New England. Descriptions of certain species of DIURNAL LEPIDOPTERA found in the United States. BY WM. H. EDWARDS. Hesperia Wakulla, n. sp. Male. Expands 1 T 3 „ inch. Upper side olive brown; primaries have an irregular row of six small, angular spots, commencing on the costa one fourth the distance from apex to base and running nearly parallel with the hind margin to middle of the wing; secondaries immaculate ; fringes long, whitish, cut with brown at tips of nervures. Under side of primaries olive brown ; the spots indicated on upper surface are here enlarged, distinct, yellow white and nearly of equal size, the fourth from costa, only being minute ; at the lower end of these spots and anterior to the line is sometimes a larger, indistinct spot with a small one below, making eight in all, extending nearly across the wing ; a minute spot at end of cell. Secondaries brown, with a grey violet tint except near abdominal margin; the disk crossed by a tortuous, connected row of irregular yel- low-white spots, from outer angle to near abdominal margin, dilated at the extremities ; a branch from this row connects with a spot at end of cell ; the nervures of the disk yellowish white, giving with the spots a reticulated appearance. Body above brown; antennae brown above, annulated with yellowish below ; club black above, yellowish below. From three males received from A. W. Chapman, Esq. of Apalach- icola, Florida. Hesperia Eufala, n. sp. Male. Expands 1-fo inch. Upper side olive brown; primaries have three semi-transparent dots in a line from costa near apex and two small spots below and anterior, separated from the others by the space of a line. 312 \VM. H.

From 2 % , 1 $ , received from A. W. Chapman, Esq., Apalachicola, Florida. I learn from Mr. Chapman that a specimen of Tlmetes Elevrha, Hiibner, has been taken at Apalachicola; it is a Cuban species, and not hitherto known to belong to our fauna. HE8PERIA Melane, n. sp. Male. Expands 1-^ inch. Upper side brown more or less tinted with fulvous, especially at base of primaries and over whole surface of secondaries ; primaries have three small fulvous spots between the sub- costal nervules, a fourth, minute, in a line with these, but separated ; two large angular spots on disk and another on edge of inner margin ; all these spots forming an irregular row across the disk. Secondaries have a row of indistinct fulvous spots nearly parallel to hind margin. Under side brown with a yellow tint, most decided on secondaries ; spots on primaries repeated but paler and enlarged ; on secondaries dif- fuse, forming a broad yellowish band. Body brown above, beneath yellow ; palpi yellow J antennae brown above, yellow below ; club black, tip ferruginous. Female. Expands l T ^j inch.
